The invention relates to .filtrationof fluids and monespecifica'lly', refers to-thefiltration-of tobacco smoke. The nitration of'tobaccosmoke isadit- :ficult undertaking because three phases; namely. zgafi, liquid and solidareincalved.
Burning-tobacco the dorm of a cigarette is fa eracking process and not-restricted to campus tion. [Petal combustion of organic mattergsueh as tobacco would lead to carbon dioxide-and water as final results and they would he harmless :and would not require filtration. Such a total combustion takes place at the burning end of theeigarette. 1
Smoke which is drawn into the mouth (is chemically a complicated mixture. influence of the approaching burning -zcne, tobacco is cracked chemicaily and very unstable chemicals, such as pyridine bases, are set free. Pyridine, with a boiling point slightly higher than that of water, will distill 'ofi asva por and shortly afterwards form of tiny droplets which are, as-
such, carriedaway with the smoke stream. 'Tars, their boiling point being higher than that of pyridine, will form droplets more quickly .but'will also be partly caught in the draft, especiaily when more than half of the cigarette has been hunted away.
Aromatic oils of high molecular weight. will evolverfrom unburned tobacco and will he carried away especially by water vapor in the smoke stream, the watervapor-comingf-rcm the fire'zone or from the moisture oftthe tobacco. Solid particles-like soot and ashes from the cigarette paper and nitrous gases from the decomposedinitrate of gaminonia'in the cigarette that'is smoke? v In accordance-with'the invention a filter paper having a high wetrtrengthfiin the form of a fiat circular disc is provided. The filter is adapted' to be folded twme tapmducea 60 filtrpaper cone which has three layers on one side and onelayer on the other;
Providing the .filterpaper in; the-dorm; of a filterpaper'd-isc has the adv-amtascthat filter-paper discs can .bel'tucked' into the. cellophane jacket of the pack of cigarettes.
.It was found during the development of this cigarette holder that it is of greatest importance to avoid by-passing of the filter by the smoke.
In the present invention the smoke necessarily passes through the filter itself. Therefore the filter must be sealed within the smoke conduit so that the filter efiects a strict partition thereof. Another sealing problem is created when a. cigarette holder into which a filter is to be Under the per join th 2 inserted comprises :two parts which are domed aiter the insertion of the filter.
, In accordance with the invention, .a filter is :used which has a conical :form formed :by folding a filterpaper disc twice which results :in a 60 paper tunnel constituting an ideal sealing means.
In accordance with the invention, this :funnel .is :usedin a cigarette holder as "a gasket between a 60 female element on the outside of the rim thereof and a male 60 element on the inside of :said :rim.
".Ilhe nature and advantages :of the present inwenti'on hevapparent from the .following ideecription taken in conjunction with the accompanying drawings, wherein:
Fig. 1 shows a cigarette holder in side elevational view with a cigarette inserted.
2 shows in vertical section part .of the cigarette holder of .Fig. 1 and illustrates by arrowsthesflowof the smoke.

Fig. 10 is an exploded'eievational-viewshowin elements of the cigarette ihol'der i lhistrated V iilfzis'raperspcct'ive'uiewsshowingthefilter paiper discs'in the :celiophane jacket of a pack mi'cigan'ettes; i
:descrilrlm'g' thehcilder as shown in 1-5 and applying the as primedto-corrparts of: the other motzli-fioatisons, I describe my invention as follows:
The cigarette holder comprises three parts; the mouthpiece IS, the main body Sand a cap 5 having a cigarette receiving socket at its outer end.
It was found necessary to apply pressure to compress the rim 2 of the filterpaper cone l to form a gasket between the female 60 flare 4 on the outside ofrim 2 and the male 60 annular ing position. the filter it reaches the mouthpiece l9 through 25 as seen in Fig. 10 allows a coaxial fitting between these two 60 gripping elements 4 and B.
An outstanding factor of the invention is that the filterpaper cone I is only fixed at its rim 2 and that the rest of the filter body protrudes freely into the space through which the smoke passes. This is made possible by a cylindrical section [5 adjacent to the 60 flare 4. Consequently, the wall [6 of part 3, while also retaining the design of a 60 funnel, do not contact nor support the filterpaper cone.
Figs. 2, 4 and 6 illustrate a cylindrical wall section at the outer end of the body 3, provided with gripping means 20 which engages gripping means 2| formed on the cap 5.
The ejector ll, referring to Fig. 4, may comprise a body 9, a turned end 13 acting as a stop with respect to the end portion 50 of the cap 5 and the ejector H is also provided with 2. turned end l2 which, in the smoking position, also cooperates with the turned end Ill. The space [4 is ample to receive theejector l i in normal smok- After the smoke passes through passages l7 and 18.
The cap 5 is characterized by a tubular socket "I, flared at its open end, for receiving the. cigarette 8. Fig. 6 illustrates a modified form of the cap 5 wherein the socket projects outwardly from the cap.
. Referring specifically to Figs. 7-10, I have provided a counterweight constituted by part 23 to balance the weight of parts 3 and 5" and I designed a functional grip by creating'a double wedge by a double-cone exterior contour of parts 3" and 23 as shown particularly in Fig. 9. The holder is carried by wedging this double cone between two fingers. In effect, this double-cone contour comprises two coaxial frusto-conical sections arranged in opposed relationand pointing toward each other and in juxtaposition one with the other. The cap 5" may be knurled at one part of its periphery as at 24.
As filterpaper I use high-grade laboratory wet strength filterpaper which is creped to form a crinkled surface. Such a paper has a certain compressibility and this allows the three-layer wall thickness of the rim 2 to be reduced to the thickness of the one layer of the opposite side of the rim when parts 3 and 5 are joined.
It will be obvious to those skilled in the art that various changes may be made without departing from the spirit of the invention and therefore the invention is not limited to what is shown in the drawings and described in the specification but only as indicated in the appended claims.
I claim as my invention:
1. A cigarette holder comprising a mouthpiece at one end thereof, a body member supported by the mouthpiece and extending axially therefrom, a filter element of compressible sheet material, and a cap member adapted to support the filter at an end-portion of the body member and having socket means at said end to receive and support a cigarette to be smoked, said body member 4 and said cap having complementary frustoconical exterior and interior walls and said filter element having folds to provide a cone with a substantially similar frusto-conical wall portion, said cap member having an annular wall member connecting the cigarette receiving socket with the frusto-conical wall of said cap, one portion of said filter comprising a single layer and the remaining portion of said filter comprising plural layers; the frusto-conical walls of said body member and said cap member being adapted to receive the single and plural layers of said filter to grip and compress said plural and single layers to such an extent as to form a seal impervious to the passage of air, whereby when said cap is placed on said body member with thefilter element therebetween and a cigarette is placed in the socket the only gaseous material reaching the smokers mouth will be that drawn through the cigarette and the filter. 2.'The combination of claim 1, wherein said body member comprises cylindrical as well as conical portions, one of said cylindrical portions maintaining a frusto-conical portion of the body spaced from the filter adjacent the seal, and another of said cylindrical portions having'means thereon adapted to receive and retain said cap to press said filter between said cap and body member thereby providing said seal.
3. The combination of claim 1, wherein the body member has a second inner frusto-conical member having its small base in axial juxtaposition to the smaller base of the outer frustoconical portion.
